Paper 233-30 An Introduction to SAS Character Functions (Including Some new sas 9 Functions) Ronald Cody, Introduction SAS software is especially rich in its assortment of functions that deal with character data. This class of functions is sometimes called STRING functions. With over 30 new character functions in Version 9, the power of SAS to manipulate character data is even more impressive. Some of the functions we will discuss are: LENGTH, SUBSTR, COMPBL, COMPRESS, VERIFY, INPUT, PUT, TRANWRD, SCAN, TRIM, UPCASE, LOWCASE, || (concatenation), INDEX, INDEXC, AND SPEDIS. Some of the new and exciting Version 9 functions that we will cover are the "ANY' and "NOT" functions, the concatenation functions (and call routines), COMPARE, INDEXW, LENGTHC, PROPCASE, STRIP, COUNT, and COUNTC. How Lengths of Character Variables are Set in a SAS Data Step Before we actually discuss these functions, we need to understand how SAS software assigns storage lengths to character variables.
